The PQ3 is a high performance integrated communications processing system based on the e500 core, which is an embedded RISC processor that implements the 32-bit Book E definition of the PowerPC architecture. For details refer to: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8555E This port was tested and successfully run on the following members of the PQ3 family: MPC8533, MPC8541, MPC8548, MPC8555. The following major integrated peripherals are supported: * On-chip peripherals bus * OpenPIC interrupt controller * UART * Ethernet (TSEC) * Host/PCI bridge * QUICC engine (SCC functionality) This commit brings the main functionality and will be followed by individual drivers that are logically separate from this base. Approved by: cognet (mentor) Obtained from: Juniper, Semihalf MFp4: e500
